Rotolock Tapered Mandrels

For grinding and turning splines, Thread Check offers expanding key type and rotalock mandrels. The rotolock mandrels are suitable for side fitting splines with clamping on the side flanks. Expanding key type mandrels are suitable for major diameter fitting splines. Thread Check also offers helical spline fixture gauges and setting ring gages which measure between balls of an internal helical splined component. Thread Check also offers a wide selection of tapered and helical splined mandrels which are used to check major and minor diameters and tooth thickness. Involute or serrated tapered splined mandrels determine the pitch line location of component internal splines. They can be used to inspect run out of component datum faces or diameters by turning on centers.

We also offer phone support and on-site gear and spline training courses. We can visit your plant to troubleshoot gearbox design and manufacturing issues and design complete gear boxes and gauging methodology. Thread Check Inc. can supply gear and spline production measuring equipment as well as sourcing for gear and spline component parts.
